I would recommend you sell the items separately, this gives you the highest chance of success.

I could take the 5D II body for my son. Let me know what you expect.

You can find a Pentax body for 6-7000 euro. I bought myself a H4D40 for 9,000 euro.

The Hasselblad body is a bit more expensive, but there is more choice of second hand lenses on the market. Resale is also bettter. be carefull a new Pentax body will probably be announced in a couple of months.
